Hey everyone! I recently upgraded my PC to Windows 11 and have been running into some memory issues. Today, I noticed that according to the Task Manager, my installed RAM has dropped to just 16GB, even though I originally configured it with 32GB. It was working perfectly fine under Windows 10, so I'm not sure if there's a problem with my hardware. Additionally, the memory toggle in Windows 11 is off and I confirmed I'm using a 64-bit version. In the Task Manager's performance tab, it shows that I have 6GB in use, 9GB available, 5GB cached, and 10 out of 32GB committed. Is this behavior expected, or is something else potentially affecting my RAM? I'd prefer to have full access to my memory again. Cheers! Also, I checked the results from HWMonitor, which I'll link below.

This doesn’t sound normal at all. The numbers you've provided don't line up, which is odd. It might be worth your while to take a screenshot of the Task Manager for better clarity. I recommend using Resource Monitor to see which processes are using the memory. You can see more details there by enabling the memory type columns and sorting them by usage.
Have you tried reseating your RAM sticks? Sometimes, a loose connection can cause detection issues. Also, make sure they're recognized in the BIOS.
I was hesitant to do that because it's tough to access behind the fan, but since this happened after the update, I’m starting to wonder if a setting has changed.

Thanks for the tip! Here are the links to HWMonitor and Task Manager for reference: https://imgur.com/a/4OWqWhP and https://imgur.com/a/ReTnj0G.
